Two questions... I've been struggling with break issues since putting a ton of work into my CJ. Prior to the work it had mostly been sitting for about 3 years.
I did NOT have any issues until I changed out my front lines. The do not appear to be leaking. I bled and bled and then bled some more and never maintained pressure. I came to the conclusion that my problem was the master cylinder and bought a reman master cylinder. It is now leaking between the master and the booster. Is this a bad master cylinder?
Second question. My brake light is always on in the speedo. I'm not sure the above is connected. Is there an adjustment on the parking brake that I am missing?

Yes, it should not be leaking there. Did you possibly damage when installing?

How were you bleeding the original MC?

I have the light problem also, there is a wire on the back of the emergency brake pedal that is pretty hokey. My is usually on but flickers, I just ignore it, I have bigger problems to deal with on it.

On the late 70's cj and newer, I believe there is a sensor on the brake pressure divider block that will also trip the brake light if there is air in the line. I remember reading about it when I was doing my rear brakes the other day.

Sorry meant to respond back to this a got busy with other things. Thanks for the responses, I still have the same issues going on as I haven't had time to work on it the past couple weeks but I think...I think I have found my air issue. I bled the m.c. per the instructions. I'm thinking maybe there is remaining air in it and now that I solved my leak problem I just need to bleed the system again. With any luck my brakes will work and that damn light will go off. Then I can move on to my next problem
